Abstract

In this paper, W-type SrCo2Fe16O27 hexaferrite nanostructures were synthesized by Sol-gel Auto-combustion method. Effect of Annealing Temperature on the structural, magnetic and Optical Properties of these SrCo2Fe16O27 nanostructures was investigated. In order to determine the Annealing Temperature of samples, the prepared gel was examined by thermo-gravimetric and differential-thermal analyses. Morphology and crystal structure of the prepared samples were characterized by field emission scanning electron microscopy and X-ray diffraction pattern. Based on X-ray diffraction results, at Annealing Temperature of 1000 ° C, the maximum amount of main phase formed. A planar morphology was spectroscopy for the synthesized samples through scanning electron microscope images. Fourier transform infrared analysis was used to confirm the synthesis of the main phase. Results confirmed the formation of tetrahedral and octahedral sites as the important characteristic of hexaferrites. Magnetic Properties obtained of samples were measured by the vibrating sample magnetometer and the results showed that by increasing temperature, magnetic saturation increases. Moreover, Optical Properties of samples were investigated by ultraviolet– visible absorption and photoluminescence spectroscopies. The result of measurements of the energy gap approximately is same in the ultraviolet-visible and photoluminescence spectroscopes and also the energy gap is constant with increasing temperature.
